Is there any delayed reaction of ceftriaxone such as dyspnea?

There is an entity called delayed allergic reaction which typically occurs hours after a dose of the drug (as opposed to immediately after the dose).

You can also develop an allergy to a drug at anytime so a drug you once tolerated you are now allergic to. Allergy symptoms include hives, shortness of breath, wheezing, anaphylaxis, etc.

In brief:
